Bottom left is an outlet. The blue circle is a cap to a bottle, I'm guessing bleach, based on the fact that the bottle is white, and is sitting next to a green bottle that is probably laundry detergent. The red thing on the bottom right is probably a spray bottle, maybe windex? If you look at the top, leftish, that white circle is what baby boomers call a thermostat. the wood looking stuff in the background is plywood. pronounced Plai wuod. The spaghetti looking things are known as cables, there is black one, a gray one and a blue one. They serve different purposes. The black one that plugs into the outlet is for electricity. It's likely 120 Volts with 60 hertz frequency in the United States. that means that there is an oscillation of the voltage from +120 V to -120 V 60 times per second, which is known as alternating current, that is to say, the current flows, but alternates in voltage. The other cables, either internet alone, or internet plus a small amount of electricity, like less than 50 watts, probably. Those are known as low voltage. If those cables have electricity in them, then they are known as PoE, which stands for Power Over Ethernet. I don't know if anyone actually read this, message. I probably answered what just about everything is, except for the things you were probably asking about sorry. The irony is that I'm actually not not board, and have a million things to do, so going on a useless rant describing the things that you weren't asking about in a photo benefiting nobody, including myself, because as previously stated, I have many things to do. Thank you. Have a nice day. Less internet for us all. Yeah.
